The PHREG Procedure

Statistical procedures use ODS Graphics to create graphs as part of their output. ODS Graphics is described in detail in Chapter 24, Statistical Graphics Using ODS.

Before you create graphs, ODS Graphics must be enabled (for example, by specifying the ODS GRAPHICS ON statement). For more information about enabling and disabling ODS Graphics, see the section Enabling and Disabling ODS Graphics in Chapter 24, Statistical Graphics Using ODS.

The overall appearance of graphs is controlled by ODS styles. Styles and other aspects of using ODS Graphics are discussed in the section A Primer on ODS Statistical Graphics in Chapter 24, Statistical Graphics Using ODS.

You can reference every graph produced through ODS Graphics with a name. The names of the graphs that PROC PHREG generates are listed separately in Table 18 for the maximum likelihood analysis and in Table 19 for the Bayesian analysis. When the ODS Graphics are in effect in a Bayesian analysis, each of the ESTIMATE, LSMEANS, LSMESTIMATE, and SLICE statements can produce plots associated with their analyses. For information of these plots, see the corresponding sections of Chapter 20, Shared Concepts and Topics.
